I am not sure if this is legal but I am doing it. I know it can be bit dangerous. Any advice before its too late for me?
make sure its good music
I think in control of any vehicle with two earphones -phone or music would be dangerous.
Dont think it is illegal, but I dont do it, I find it too distracting and find that I dont concentrate on the road enough. Possibly might be OK if I was doing a long motorway trip, but through central london, not for me.
But some people do it and are OK with it, personal choice I reckon. Also depends on what music, how loud, etc.
I only do it on long motorway journeys and I keep one ear free to listen to the traffic.
Theres no law saying you cant listen to music while riding, i tried it and didnt like it much. Id rather listen to the music coming from the bike.
I listen to tunes through my satnav on long journeys. I have shure in-ear 'phones that have better noise blocking properties than any earplugs I’ve ever used!
I listen to music via my Autocom system and with the automatic VOX setting it increases/decreases the music as you increase/decrease speed. This means you set it a comfortable volume before you leave (i.e. where you can still hear what is going on around you) and it’s not intrusive at all.
It’s not illegal in itself, however if you were sufficiently distracted by the music you could be termed ‘not in proper control’ (which I think is now an Endorseable Fixed Penalty Notice (FPN) £60, 3 points) or worse driving without due care and attention (visit to the Magistrate, 3-6 points, sizeable fine, discretinary disqualification). If you ride one of those big bikes with built in sounds and speakers, and crank up the volume you could also find yourself breaching regulation 97 of the Construction and Use Regulations, causing or permitting a vehicle to make an uneccessary or excessive noise (Non-Endorseable FPN £30 No points).
However proving that listening to your tunes whilst riding had caused distraction or a lack of care would be very hard.
I used to be dead against this when I was first riding, but now I ride everywhere with music as I do so much commuting. I don’t have it loud so I can still hear traffic, other riders and sirens and I use my mirrors and life saver a lot more.
Definately personal choice 
I have the ipod going while I ride, loud enuff to hear but not so loud as to block out everything else. Better than wearing ear defenders I think but as GG says it’s all personal choice. 
I’ve never done it myself but i remember when i started racing there was a lad who used to listen to music when out on track, and it was always ‘Two Tribes’ by Frankie goes to Hollywood
From what i saw, it didn’t work for him.
On the road i think it might help you relax but it could be a distraction.
lol.
I agree wiv gridgirl
If you listen to music don’t have it turned up to loud! unless your on the motorway
There is only one noise I want to hear - my pipe SCREAMING IT’S LUNGS OUT!
i see no difference it makes to being safer on a motorway though.
There is no specific law regarding listening to music.
‘Not in position to have proper control’ has been touched on but unless you actually admitted to Police that the music distracted you they are not even going to try to prosecute that.
The ‘distracting’ element is only present when you have the volume at such a level that you numb out all outside sounds which would then put you at risk.
However, if you are a regular wearer of earplugs you also numb out outside sounds but not so much as to be a risk, bear this in mind when adjusting volume and your sorted.
finally, the music you listen to can influence your riding style…for example, listening to something along the lines of prodigy - Firestarter can make you a tad more aggressive, listening to the BeeGees - How deep is your love will relax you and calm your ride…
but,ultimately it’s not illegal.
P.s. the two example of music i just mentioned are not mine.
I find that having music on makes me more attentive visually but it is a bit of a phaf in town espcially if you need to communicate with othe road users or lemmings.
Great on the motorway also a good way of quantifying the time traveled.
Down to the idividual ultimately
I listen to my ipod and I have a remote attached to my handle bars where I can start, stop change tracks and adjust volume.
It is not distracting but just back ground noise and sure beats wind noise.
I usually ride with ear plugs in so no point asking me…lol
